I've tried to preview my final render, however I've noticed that the shadows are casted incorrectly. The problem isn't the positioning. Moving the lights doesn't affect shadows and only makes already illuminated areas brighter if the light source is near them. But even if I put the point light in front of the face, the shadows aren't modified at all. I've tried strenghtening the light and changing its size, however the shadows are still wrong.

Is there any step I've missed? How can I fix this?

Shadows are casted wrongly, just like on this screenshot Seen from other perspective

  • $\begingroup$ @JacksonPro check the other pic I uploaded. The problem isn't the positioning. Moving the lights doesn't affect shadows and only makes already illuminated areas brighter if the light source is near them. But even if I put the point light in front of the face, the shadows aren't modified at all. $\endgroup$ Commented May 7, 2020 at 20:52
  • $\begingroup$ Try to make the light size smaller. If the object fall off the light radius it won't be affected. $\endgroup$

  • $\begingroup$ @Carlo I tried that, placing the face into the light's radius but that didn't work. The shadows didn't change at all and already illuminated areas just got brighter. $\endgroup$ Commented May 7, 2020 at 21:58
  • $\begingroup$ Are you sure that those are shadows? Could you upload your file for inspection? $\endgroup$

Incomplete node setup

Normal maps need a conversion before you feed them to the shaders. The black spots you are experiencing are not shadows, but an incorrect calculation of the surfaces normals.

A Normal Map node must be added between the texture and the shader.

As said in the manual:

The Normal Map node generates a perturbed normal from an RGB normal map image. This is usually chained with an Image Texture node in the color input, to specify the normal map image.

enter image description here

  • $\begingroup$ Oh I see. I didn't know I needed to do that to begin with, and it was indeed the problem. So then should I do this everytime when I import an object with a normal map? $\endgroup$ Commented May 8, 2020 at 22:12
  • $\begingroup$ For the common Normal maps, yes you should. $\endgroup$
